this is not a bug - this is simple recursion. What did you expect would happen?

I think to have to same expect "__construct"

Test Script:
---
<?php

class A
{
    public function __construct()
    {
        new static();
    }
}

new A();
----

Expect:
---
Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 262144 bytes) in /path/to/test.php on line 7

Duplicate of bug #64196 (for __clone, but the root issue is the same for all of these infinite recursion stack overflows).
